Hope you are well. What I understand from your description is that you are looking for someone who can handle your Amazon FBA account fully and do tasks like, deal with hijackers, open cases with amazon and run PPC campaigns when you need.
The person must also be able to provide you with Performance reports of your account, financial reports and PPC reports if needed. Provide customer support and handle returns (In short all the tasks of a VA).
